Abstract (en)
An ink jet printer and its recording method. A control for varying a feeding pitch of a recording sheet and a control of ink ejecting of each nozzle are performed. On the condition that there is no common divisor between the number of nozzles n and a pitch interval between nozzles m and that a relationship of n=pm+q(p≥1,m≥2, 1≤q≤m-1) is satisfied, recording operation is performed as follows: after all mxn lines are recorded by one pitch feed, n pitch feed is performed while only the nozzles not overlapping the recorded lines are allowed to eject ink. After the n pitch feed is performed m-1 times, each n pitch feed is performed while all the nozzles are allowed to eject the ink. All the recorded lines are recorded without being overlapped or generating any gap. No non-recorded area is generated in a top end of the recording sheet. The effect use of recording sheet and the enlargement of recorded area can be realized. At the i-th (1≤i≤m-1) n pitch feed, Äixn/mÜ+1 nozzles, represented by Gauss' notation, from the downstream side (terminal end) in the recording sheet feeding direction are allowed to eject the ink. <IMAGE>
